Background technology
Most widely used insertion-core lock is the kappa lock at present.Kappa lock has generally comprised lock body, lock core column, pellet and spring, clutch part and pull out sheet.The pellet of kappa lock is cylindrical, in lock body and lock core column, corresponding marble hole is arranged, each marble hole has two cylinder-shaped marbles and a spring, pellet inserts between lock body and lock core column by the pressure of spring, pellet divides spring marble and key pins, always in lock core column, spring marble one end contacts with key pins key pins, and the other end is connected with spring.Under spring action, spring marble is stuck between lock body and lock core column, lock core column can not be rotated and be in locking state.The degree of depth of the length of key pins and the opening of key is corresponding, and the opening of the long key of pellet is just dark, otherwise shallow.After inserting key, key pins is got up by the open top of key, the contact surface of key pins and spring marble is just in time parallel with the lock core column periphery, be also that key pins is fully in lock core column, and spring marble is fully in lock body, do not have pellet to be stuck between lock body and lock core column, so lock core column can rotate, thereby lock is opened.If not original key, as long as a pellet is arranged between lock body and lock core column, block lock core column it can not be rotated, lock is not just opened.But kappa lock marble amount very little, generally only has 6 or 7, is easy to by technical opening; And lock core column is powerful to be reversed if insert with instrument, and the pellet that is stuck between lock body and lock core column is easy to destroyed and lock is illegally opened.Especially recently popular simply wield " hitting spoon " technology, can open the kappa lock of pellet up and down by very quick not damaged.Remove the bump key pellet with a special spoon that hits, key pins is then clashed into spring marble, and key pins one end is subject to hitting the shock of spoon, and the other end is subject to the back-lash of spring marble and hits, and during both balances, makes key pins almost motionless; And after being subject to the shock of key pins, spring marble jumps up, thereby separates with key pins, be retracted in lock body fully, so lock core column can rotate, thereby lock is opened.
In a word, present insertion-core lock, marble amount is few, be easy to by technical opening, and the locking between lock body and lock core column is to be stuck between them by pellet, and pellet is easy to be made by powerful torsion failure lock illegally to be opened.
Moreover the insertion-core lock overwhelming majority is by the brass manufacturing, uses the battery-type electric hand drill, just can bore lock core bad in two minutes and a lock is illegally opened, and theftproof performance is poor, also is easy to be opened by technology, as firmly prying open or destroying with electric drill and open.
at present, the hinge of most of hinge locks is all slided, for example Chinese patent 002273713, 012715077, 032683383, 982348797, 982430434, 992408016, 2004200144296, 2004200954473, 2006201658334, 2007200625906, 2007200629042 hinge is parallel-moving type, hinge is translation to the left or to the right under the promotion of key bit, Chinese patent 01266248.8, 200620033856, 200710079076, 2003201316920, 2006200549626, 2006200570398, 2007201524071 hinge is to slide along the circular periphery of lock core.The hinge of most of hinges lock does not all have turning cylinder, and hinge is not to rotate around turning cylinder, and such hinge lock is smooth and easy not, when the size of lock hour, for example " insertion-core lock " during small size, the hinge lock is just smooth and easy not like this.
Chinese patent 2009201571442 has proposed hinge has the hinge of turning cylinder to lock, hinge is rotated around turning cylinder, therefore, such hinge lock should be more smooth and easy, but because this design need have a lock core, in most cases, the length of lock is conditional, and lock core has the certain thickness interval, the hinge quantity of laying in the lock of same length is reduced, thereby cause safety not high; Lock core must pass hinge, and guarantee each hinge and mutual relative position of lock core when lock gall dallies remains unchanged like this, otherwise cisco unity malfunction; But lock core passes hinge, makes hinge become the semicircle annular, greatly weakens the flexural strength of hinge, and when inserting or extracting key, the thrust that produces hinge can make the hinge bending of semicircle annular and cisco unity malfunction; And if the dimensions scale downward that will lock during to the insertion-core lock size, the size that hinge promotes the position by key is only more than one millimeter, is easy to be pushed away by key curved, therefore is difficult to be applied to insertion-core lock; In addition, the lock core front end of this patent (key insertion end) is structure silently, so rotating shaft must insert from the rear end, can't add anti-drilling lid, can't accomplish anti-drilling.
